I have heard about the engine braking with a four stroke and was wondering how that might affect you on a jump. My 125 is nice bc I can just move it around under me very easily for example scrubbing. I would imagine that would not be so easy with a heavy ... more »

I'm considering buying a new (2016 or 2017) 250f in the spring. I grew up racing from 8yo until 16yo, and recently started riding again on a yz125. The 125 is a blast and will probably always keep it around for when I get the urge but I want something ... more »

So went through the carb again. Blew the whole thing out and took it all apart. I ended up replacing the needle valve seat for the float. The o-ring must have been no good anymore because the old one set in with no resistance and even had a small amount ... more »

theonlinelegend haha yeah I thought that right after. Didn't know it would though until it did it the second time. So needless to say I just went in circles on flat ground for a bit. I have boyesen power reeds in it.

Forgot to mention this. The cover to the power valves had one of the screws back out all the way and was just hanging there. There has been a good bit of oil/sploog coming from it. So I thought maybe it was sucking air so tightened that best I could ... more »

I've adjusted the tab on the float a couple times now and I've gone pretty far with it with no changes. I started to wonder about the gas cap since it will be sitting on the stand and I can sometimes hear a gurgling sound coming from it like it's releaseing ... more »

Alright, so I'm not the most mechanically inclined but I somewhat know my way around 2 strokes. I have a 2002 yz125 that will start and run pretty crisp for about 1-2 minutes on the stand, then I put in first, take off and before I can even make it a ... more »
